HULLEBv-GIN- the'material is more effectively and expeditiously ginned with less waste.

A further object of the invention is to provide 'a huller gin having a continuous operation and wherein the necessity of dumping is avoided. 4

The essential feature of this improved gin isth provision of means for moving the material to be ginned longitudinally of the hulling chamber toward an enlarged exit or outlet, which in the present instance is located at the center of the machine, and whereby the residuum or hulls eliminated from the cotton which would otherwise accumulate and clog in the hulling chamber are fully relieved from the said chamber without requiring manual attention.

The invention further contemplates the construction, arrangement and combination of mechanical elements and devices contrib .uting to the performance of the ginning operation and which will be more fully hereinafter described and claimed in preferred form.

illustrating the end wall assemblage of the chute with one of the ribs and the relative position of the next adjacent rib.v Fig. 9 is a detail perspective View of one of the ribs used at a point away from the central portion of the gin. Fig. 10 is a detail View of a portion of, the huller roller showing a modification.

The numeral .5 designates the end legs which are of a contour adapted to receive and support the working parts or ginning devlcesas well as the hulling chamber and roll box and, connected .by any suitable means to render the gin'organization stable as well as. strong and durable. The improved gin also includes a brush cylinder 6, a saw cylinder 7, and aroll box 8 having a roll impeller 9 therein, the brush cylinder cooperating with the saw cylinder in" the usual manner and operating to direct the lint cotton intoa tube or flue 10. In front or advance of the saw cylinder 7 and roll box 8 is a hulling chamber 11 providedwith a huller roller 12 in its lower portion in operative adjacency" to the saw. cylinder 7. Between the roll box 8 and the rear lower portion of the hulling chamber 11 and in operative relation to, the saws of the saw cylinder 7 is a plurality of ribs 13,14 and- 15, the ribs 13 extending from the opposite extremities of the gin inwardly toward the center to the ribs 14 and the ribs 15 disposed between the said ribs 14 in a manner and for a purpose which'will be more fully hereinafter explained. The ribs 13 and 14 are essentially similar in construction, but the ribs 15 differ materially from the ribs 13 and 14. Below the ribs 15 and also located between the lower extremities of the ribs 14 are guards 16. which have ari upright disposition and cooperate with the seed exit or outlet, as will also be more fully hereinafter specified. The front wall 17 of the hulling chamber 11 is suitably pivoted at its upper extremity to permit itto be swung out of the way or opened in the ordinary Way, and to the inner portion of the said wall a lambrequin 18 is adjustably attached and operative in the usual manner through the said Wall 17, as for instance by a latch 19.

The huller roller 12 is mounted upon or fixed to a shaft 20 having suitable bearing in the. opposite ends 'or heads of the hulling chamber and provided on one end with a band wheel or pulley 21. This huller roller 12 may beprovided with either broken spiral flights 22 or, as shown by Fig. 10,

with a continuous spiral flight 23 having spikes or pins '24 standing outwardly therefrom at intervals around the circumference of the roller. It should be understood that when the spiral flight or flange of the huller roller is arranged in a continuous unbroken spiral, it will not be" thoroughly-effective asa means for causing a rotary movement of the material. Soarranged, the spiral would be somewhat disposed to cut through the material and while being thoroughly effective in moving the material lengthwise along the hulling chamber it would lack thoroughness and efiectiveness' in moving the material toward the saws and imparting thereto a rotary movementunder maximum feed conditions, and, therefore, when the spiral device 23 is fixed to the huller roller in a' continuous 'unbroken form,

the saw teeth. I

as ,shown by Fig. 10, theg spikesor pins 24 are necessary to secure effective rotary movement of the material for moving; it against 4 the spiral :flights or flanges are fixed to the huller roller 1n separated sections as at 22, as shown by Figs. 2 and 3, then the spikesor pins wiflnot be necessary as the cut, broken or separated spiral. sections will be thoroughl efficient in imparting a' rotary as well as a ongitudiupper portions of the ribs 13, 14 and 15 into the roll box 8. The saw cylinder shaft 26 is provided at one end with a band wheel 27 to'which power is transmitted from any suitable source for driving said shaft, and on the opposite extremity of'the shaft is a transmitting pulley 28 having a belt 29 trained 'thereover and also over a receiving pulley 30 held on a shaft 31 at the upper part of ,the'machine for controlling the direction of movement of the remaining arts-and alsoprovided with a transmitting pulley 32 over which" is trained a belt 33 extending downwardly and passed over a portion of a fixed idler 34 and thence around" the pulley 21 on the huller roller shaft 20 and from the latter extending upwardly over an idler 35 forming part of a belt tightener- 36, and then down and around a pn ley portions 49 37 on the'one end of the impelling shaft 38, and from said pulley 37 the belt 33 returns to the pulley 32; By means of the mechanism just described it will be readily seen that the several moving parts of the gin are effectively operated and given a proper direction of rotation -The outlet opening 39 of the hulling chamber is provided between the centrally reduced portion 25 of the huller roller 12 and the adjacent lower edge of the lambrequin 18, said opening beling large enough to permit free escape of the residu um or hulls at the center of the said hulling chamber. The seed outlet 40 of'the ginning roll box is in the bottom at the center of the latter and is formed between the short ribs 15 and adjustable lambrequin or valve 41 mounted in a frame 42 secured to the lower part of the breast 43 and having an adjusting latch 44 accessible through the open top portion of the hulling chamber 11. The lower ends of the ribs 15v are curved so as to facilitate the outlet of the seed. Directly under the frame 42 and below the lambrequin or valve '41 a chute 45, shown in detail by Fig. 7, is

applied between the ribs 14, which may be termed sustaining ribs. The chute 45 has a closed front portion 46 and sides 47, the said chute being provided with a longitudinal contour to renderit efiicient as a downwardly directing means for the seed through the reduced-central'portion 25 of the huller roller 12. The inner opposing sides of the ribs 14 at the points of location of the hulling extensions 48 are provided with bracket having outwardly projecting attaching ears 50 and elongated bearing edges 51. Between the extensions 48 and engaging the brackets 49 the upper extremity of vthe chute 45 is inserted and secured to the said ears 50, the lower end of the chutehaving laterally projecting ears 52 which are secured to the lower .rib rail 53. The lower end of the chute 45 also has adownwardly inclined flange 54 to which-and the lower edge of the rail 53 a suitable tube or outlet conduit 55 is secured. I

At an intermediate point the wall 46 has a casting 56 secured thereto and serving as an apron which projects downwardly into the intermediate reduced portion 25 of the huller roller 12 and prevents the hulls 0r escaping material from accumulating between the lower portion of the wall 46 of the chute and the adjacent portion of the inner circumferential wall of the reduced portion of the roller 12. The upper terminals of the guards 16 stand approximately in vertical alinement with the lower terminals of the ribs 15 and prevent theseed falling through the opening 40 and striking the portion of the wall 46 opposite the said guards from being thrown rearwardly out of the confines of the chute and thereby obviate loss of the seed between the saws. It will be understood, therefore, that the difference between the ribs 13, 14 and 15 is that the ribs 14 are particularly constructed to support and hold the chute 45 and the ribs 15 are shortened to form the bottom outlet or seed escape opening 40 for the ginning roll box. Each of the ribs 13 and 14, how-'- ever, has an upwardly and forwardly, pro-- jecting hull deflecting edge 57 which extends beyond the maximum projection of the saws of the saw cylinder, and above the said edges the intermediate portions of the ribs are laterally extended or formed with small integral plates or tables 58 which lie in close relation when the several ribs are assembled to obviate lateral movement of the intermediate extended portions of the ribs.

As shown by Fig. 2, the hulling chamber 11 is provided with suitable feeding means 59 adjacent to opposite extremities and the machine, as will be more fully hereinafter described, moves the material as acted upon toward the center of the gin so as to freely and quickly liberate the larger hulls or residuum through the opening 39, and at the same time permit the saws to effectively remove all of the cotton which may be mixed or in transit with the hulls before the latter reach the central outlet opening or discharge, Smaller portions of hulls may also freely escape between the saws in the well known way, or along the huller roller in front and rear thereof.

The ribs at the opposite extremities of the hulling chamber have openings 60 therethrough in the regions of the hulling extensions 48 of greater width than the corresponding openings 61 between the ribsadjacent to the center of the chamber to permit the cotton to rapidly pass from the hulling chamber'to the roll box to obtain a maximum intake capacity immediately under the feed means 59. Near the center of the hulling chamber adjacent to the outlet there is but little cotton left among the hulls and consequently the openings 61 are not as wide as the openings 60.

In operation the bully cotton is fed into the hulling chamber 11 and falls or gravitates upon the huller roller 12 and is thrown up'by the latter against the saws of the cylinder 7, the said saws picking up the cotton as it is thrown thereagainst and pullingthe same through the ribs into the ginning roll box 8, the hulls when thrown up being intercepted by the adjacent edges of the ribs and deflected and thrown over by the upper edge portions 57 and then again brought back or thrown up into contact with the saws, and at the same time, by the action of the spiral flights 22, they are moved longitudinally through the hulling chamber toward the central outlet or discharge 39. The mass of hully cotton or of the shells entering and remaining in the hulling chamber until discharged is not only fed lengthwise through the said chamber toward the central discharge opening, but also at the same time given a rotary movement, therebypermitting the saws to effectively remove the cotton from the hulls during the transit or feed of the latter toward the said outlet or discharge opening. The rotary movement is given to the material within the hulling chamber by the cooperative action of thehuller roller 12 and the saws of the saw cylinder, and longitudinal movement is imparted to said material by the spiral device or devices on the huller roller. During this operation the smaller portions of hulls will escape from the hulling chain ber in the usual manner, whereas the hulls and foreign bodies too' large to escape by the usual outlet means are moved toward and liberated through the central outlet or discharge opening 39. The seed cotton carried up into the ginning roll box 8 is subjected to the usual ginning operation to separate the seed and thoroughly clean the latter or free the same of lint, and the lint cotton is thence taken by the brush cylinder 6 from the saws of the saw cylinder in the ordinary way.

It will be understood that the movement of the material longitudinally of the hullingchamber as well as the rotary movement imparted thereto and a continual throwing upward of the material against the saws result in a practical removal ofthe seed cotton from the said material prior tothe discharge of the latter through the outlet opening 39. It will also be understood that the movement of the material lengthwise of the hulling chamber ensues similarly from opposite ends thereof toward the intermediate or central discharge opening or outlet 39. The gin is also effectively operative, as hereinbefore indicated, without requiring manual attention to avoid choking or to rectify undue accumulation of hulls. When the seed reaches the center of the ginning rollv box 8 it is prevented from becoming inert by the impeller 9 which is disposed above the outlet or discharge opening 40 on the center of the impeller shaft 38, and that portion of the cotton which also moves toward the center of the ginning roll box is thrown out toward the saws and its rotary movement maintained together with the seed at a point where it might otherwise fail to have the necessary rotation imparted thereto. By

this means the ginning operation is effective 1 throughout the Whole length of the roll box and the seed will be discharged in a clean condition.
